Letters Patent No. 87,745, dated Ma/rch 9, 1869.

IMPRQVEMENT 1N MEvAstmmG-rtmmin The Schedule referred to' in these Letters Patent and making part of the same.

To all to 'whom these presents shall come:

Be itknown'that I, AHERMAN J. WOLTERS, of Salem, in the county of Essex, and State of Massachusetts, have made an invention of a new and useful Implement, Combining in itself a Tunnel and Measure and do hereby declare the following -to be a full, clear, and exact description thereof, due reference being had to the accom panying drawings, making part of this specification, and in whichigures 1 and 2 are vertical and transverse sections, an

Figure 3, a plan of the said invention.

This invention relates to means for combining, with atun-nel for guidingv the flow of liquids, a device for y measuring accurately the amount of liquid to be passed through such tunnel, and consists in the employment of a semispherical bowl or vessel, provided with a dischargingfaucet, and witha pendulous measuring-rod, suspended bya universal joint within it, from a crossbar or handle, so arranged that thev point of suspension of such rod shall be the centre of the sphere'of which the bowl forms a part, in manner and for the purpose as hereinafter explained.

In the drawings above mentioned as illustrating my inventiona denotes a bowl or vessel,'made of sheet-metal, or ,other suitable material, supported preferably upon a tripod, or legs,"b c ol,'in order to maintainit at some Aaltitude above the oor or tableV upon which it may rest, although, if desirable, these legs may be dispensed with.

The bowl )a is a portion of a sphere in form, preferably about semispherical, and hasat its bottom a discharging-faucet or valve, m, for regulating the iiow of liquid contained in it, this faucet supplying the place of the nose of an ordinary tunnel, and used substantially in the same manner.l A pendulous rod, e, is suspended within `the bowl, and from a cross-bar or handle, f, extended across the top of the same, by ymeans of a 'universal joint, g, by which free pendulous motions of the rod e in any direction are permitted.

The disposition of the cross-bar f and joint gis such that the point of suspension of the rod e, by means of such joint, shall be the centre of the sphere of which the bowl is a portion, in order that the lower extremity of the said rod shall always remain at the same distance vfrom the interior circumference of the bowl; by which means a given height of liquid within it shall always indicate the same mark or measure uponv the rod, at whatever angle the bowl may be disposed.

The rod e is to be provided with a suitable measure,

or scale, for indicating diii'erent quantities of liquid, and

should be of metal, in order to stand perpendicularly within the bowl, which it would not do, were it of less other suitable material.

When not in actual use as a tunnel, the faucet of `the implement should be closed.

It will, of course, be obvious to intelligent persons, that when a quantity of liquids is poured into the bowl, the amount of such liquid will be accurately determined by the'scale upon the pendulous rod, the implement thus serving simply the purpose ofa measure.

When required to perform the functions of a tunnel, the lower extremity of the faucet is to be inserted within the desiredreceptacle, and the faucet opened. v

In place of the faucet made as shown in the present instance, a valve should be so constructed as t close the discharging-olice of the bowl, immediately at the bottom thereof, in order to prevent 'any amount of liquid from standing within the body of such faucet. Otherwise, ifa very small quantity of liquid is to be measured, the bowl must be so disposed, previousv to opening the faucet, that liquid shall not have access thereto.

I claim as my. invention, and desire to secure' by Letters Patent of the United States, as follows:

I claim, as a combinedtunnel and measure, the semispherical bowl a, with the discharging-faucet m, and

the pendulous measuring-rod e, applied and suspended within the bowl, as explained, the whole operating in manueland for the 'purpose as herein shown and de-
